Got these cartridges and I cant tell a difference -- just used them for the first time and they printed perfect test pages. i always wonder if the non name brand cartridges will work and these did great. I know that I will getting more of these for my laser printer.

Product more than meet my expectations! Was a little afraid at first that the ink would not fit or work, but after an easy install it prints just great. A real bargain in an industry that seems to over price items!
